The game is three-man, and it gets you wasted in about 20 minutes.
7=drink to the left.
11=drink to the right
3=first person to roll a three is the three-man. Every time a three is rolled, or something that adds to three, they drink (If something that adds to three is rolled, that person becomes three-man).
Doubles=either divide the drinks and give them out, or give them all to one person and watch them puke!
N.B. Each time you drink, it's two gulps.
